Ok, then. Let's get into detail: he is thin, and, as a great actor, can play a lunatic, a charming man, a killer, a beggar, a playboy, etc.

There are others, but he could make a great Joker.

All of those things are true - however, there might be people who could do that job better. We don't necessarily need an actor who is pretty and charming. We need an actor who can pull off insanity and entertainment. I have yet to see a film in which Jude Law is funny. I have yet to see a film in which Jude Law has played someone genuinely, evilly, insane and loving it.
